当目标所处背景与目标本身红外辐射相差不大时，目标不能被准确识别。 为了能够准确定位目标并摧毁目标，提出了采用7元红外排列方法对目标进行扫描的想法。实验 结果表明，通过目标的红外特性曲线可以很准确地实现发动机位置的识别。依据典型目标的发动 机位置可判定目标类别，并能准确打击目标要害，从而摧毁目标。

When the infrared radiation from a target and its background is not different greatly, the target can not be recognized accurately. To locate the target accurately and destroy it, an idea that a seven-element infrared array is used to scan the target is proposed. The experimental results show that the position of the engine in a target can be recognized accurately by utilizing the infrared characteristics of the target. According to the engine positions in typical targets, the targets can be classified and their critical parts can be recognized and destroyed.
